In the presence of a catalytic system comprised of NiBr(2)(dppe) and Zn, arylacetylenes undergo tetramerization to form linear octatetraenes, generally in good to excellent yields. The structure of the coupling products was verified by X-ray crystallography.
在由 NiBr(2)(dppe)和 Zn 组成的催化体系存在下,芳基乙炔发生三聚反应形成线性八聚三烯,通常产率良好到优秀。通过 X 射线晶体学验证了偶联产物的结构。
